SPECIFICATION forming part of Letters Patent No. 620,866, dated February 28, 1899.

Application filed January 12, '1899. Serial No. '201.908x (No model.)

To @ZZ whom, it may concern.'

Beit known that I, ERIK GUSTAF NICoLAUs SALENIUS, a subject of the King of Sweden and Norway, and a resident of Radiator, Al-

bano, in the Kingdom of Sweden, have in.

vented certain new and useful Improvements in Tools for Assembling and Separating the Iarts of Centrifugal Apparatus, of which the following is a specification.

-This invention'relates to special shop-tools; and it has for its object'to provide a special tool for use in setting up and taking down the axially-detachable parts of the drum or bowl of a centrifugal apparatus.

In the accompanying drawings,` which illus trate an embodiment of the invention and its several applications in practice, Figure lis a side elevation of the tool, showing it in usefor removing the upper from the lower part of a centrifugal bowl or drum. Fig. 2 is a similar view showing the tool in use for removing the inset from the drum. Fig. 3 is a similar View showing the tool employed as a press forforcing the inset down into the drum. Figs. 4s and 5 are elevations of the tool as it appears when not in use,- the former being a side view and the latter an edge view.

The toolv consists of a screw a, screwing through a central nut-boss in a cross-head b. To the ends of said cross-head are hinged, respectively, two long pendent jaws c, having inwardly-hooked extremities5 each extremity having on it a shoe c2, provided at its upper and lower front edges, respectively, with a rounded nose or projection h5 for purposes to be hereinafter explained. The hinged end of each jaw c is embraced between two downwardly-turned cheeks b on the end of the cross-head b, and in said cheeks and the jaw thereare lpin-holes .c to receive a pin c when the holes in'the jaw and cheeks are brought to register, and thus hold the jaws c rigid withv the cross-head b, as seen in Fig. 2.

On the end of the screw a is secured a footpiece d, which has xed to itat opposite sides pendent hooksf. On the upper end of 'the screw is a suitable operating-handle a'.. A detachable partof the tool (seen in Figs. 2, 4, and 5) comprises'two connected hooks g g,

pendentfrom a cross-bar gf, the latter being adapted to lie in the hooks f when this part is used.

As stated,Fig. l showsthe tool in use for detaching and lifting off the upper part o f a centrifugal-drum. To the main or lower portion 7L of the drum belong the partsh', h2, and h5. The upper part 7c in setting up the drum has its neck 7o forced down over the slightlytapered neck h2 of the main part h, and to detach-it the pins c are removed, the jaws c brought under the part c, and the foot-piece d brought to a bearing on the top of the portion he. Now by driving down the screw ct the part 7c is raised and detached. In Fig. 1 parts of the drum are broken awayto show how they fit together.

In Fig. 2 the tool is represented as employed for removing an inset, so called, from the drum h, this latter and the inset p being represented in section. The jaws c are locked by the pins c', which bring the shoes o2 in the proper position for their projections h5 to engage the packing-groove in the upper edge or margin of the drum. The hooks g are made to engage holes in uprights Z, connected with the base of the inset, and the latter is drawn out by means of the screw a. J

Fig. 3 showsho'w the tool.' may be employed for pressing the inset p down into place in the drum. The pins c' areremoved, so as to allow the jaws c to spread until the upper projections h5 on the shoes c2 of the jaws take under and engage the fiange on the frame X which supports the .drum. The inset (which is mainly composed of superposed plates, well knownin this art) is placed in the drum, the cover m of the drum placed thereon, and the screw c run down: upon the part h2, (on the cover,) and sci'ew-pressureapplied until the, cover is brought to its seat on the top of thel drumr The ring p' (seen in Fig. l) is now screwed onto the drum in a well-known way.

It maybe stated that the foot-piece d, carrying the hooks f, is rotative on the screw a. I do not herein claim any feature of the centrifugal drum. The drum is illustrated herein only to show the uses to which my tool is applied. l

Having thus described my invention, I claim,- 'v
